When you create a string variable in UiPath Studio and don’t set a default, what exactly is it initialized to under the hood? I’ve done tests and here’s what happens:
IsNothing(mystrvar) => true OR mystrvar is Nothing => true
mystrvar = "" => true
Not sure how to test for null. IS THAT THE SAME AS “NOTHING”? (I come from a db background and null is something special).
So is it null, nothing, or empty? Or in UiPath, are they all the exact same thing?
